153e it known that Timone-RE Winnen',

acitizen of the United States. residing at Philadelphia, .1n the county of Ilniaoelpnia and State ofPennsyivania, nave invented certain new and useful improvements in Wheels, of which. the oliowing isa speci- Vfic-ation'.

My invention relates to improvements in wiieels, "tieni riy en im proved constinctien ef keywiiicifi entities the spokes to be seciireijvv interiocked at the heb portion of the wheel further object is 'to so construct the spoke :1t-the hub enel that it will eectnally interlock when the spokes ere piaceri to get-her, regardless or which Way the spokes are turned7 as there is no snciitiling as rights and ieitsi each' spoke locking Weil with one side as Witli ether. f

A further object is to provide improve ments of this character which may be mannof construction ani?. combinations ansi ar rangements of parte. be 'ni-ore nily hereinafter ciesciibeei anc e V claims In the accompanying iire'wi' is a broken View in side eleve the spoke assembed the iine. a View on an enlargeci seais in sills el oi one of the spokes. 3, is an sii of Fig. i?. as is an enti ifiew o b anci Fig. 5, an isometricai perspective View of one of the spokes on a reiiriced sceie All of the spokes Il, their nnb ends.. are cut precisi-ii??

spokes. @Cenone 4, on their outer faces, are sti'aigiit and the outer face of one tenon is in parallelism with the outer face of the tenon on the opposite side of the spoke. The inner faces of said tenons, Wliicli foim the bases 'of the mortises, are inclined as shown clearly in dotted lines in Fig. 2,' sol that when the tenen of the adjacent spoke is positioned in said mortise, the spokes will be angniarly positioned relative to each other andthe keystone shaped sections 3, 3, will snugly t against eachother and form perfect joint.

It wili ne noteci that there are no such `things as rights an lefts in this speke, for 'when it is reversed, its several tenons and .mortises occupy the same relative positions. This is one of the essentials of the case, as it requires 'no care in assembiing the spokes, ansA 'the keystone shape of the sections 3 insure a 'perfect assemblage, each spoke wedging between two others and the interlocking mertises and tenons preventing an Vpossiiiiiity of lateral displacement.

Various slight changes might be made in the general form and arrangement of parts described Without departing fronimy invention, and hence I Clo not limit Inyselto' the -gireeise details set forth. but consider nilgfseii at liberty to make such changes and aiteietions as airiy fali Within the spirit ansi scope 3i- 'the appeniisd claims.

*ving tlins iiesciibeci my invention, what ciann esA new anti fiesire to secure "by Let1 ters Paten" t is: A. spoke shaped at its hun end forming inner and enter sections of keystone shape, inert" and a tenen at each sie of said spokei enter edges et tnerespective tenens parailei with eac'n other, snbstantialiy as diiescriceti 2, A spoke shaped at its hui) enti forming inner and. enter sections of keystone shape, a iss anc?. a tenen at each side of 'saici l, edges ef the respective tenons paralisi. ,with each other, the inner efges oit said tenons Wlicii constitute tlie inner is of saiii niortisesinclined at an angle vgreater than the angie of incline of the sie edges of the keystone shaperi pon. tions? snbstantiaiiy as described.
